For videogame and universe lovers

For those of you who have always wanted to create their own universe this game is the ideal one.

Universe Sandbox2 in a game in which you can create and destroy your solar systems.

You choose a type of star, you put your planets arond it and you have your solar system. But that’s not all. You can experimentate and put your planet near the star, will it burn? You can put it in the habitable zone and play with the amount of carbon dioxyde to heat it up and see what happens. You can make planets and stars collapse.

Willing to see a super nova? You can lower the temperature of one of your stars simulating how it gets older and older and then… KABOOM, supernova (or red dwarf depending of the initial size of the star).

You are the god and master of your own universe. Willing to try it?

How do I Spot The Station?

What does all this sighting information mean?

SpotTheStation! Time:  Wed Apr 25 7:45 PM, Visible: 4 min,  Max Height: 66 degrees,  Appears: WSW,  Disappears NE.”

Time is when the sighting opportunity will begin in your local time zone. All sightings will occur within a few hours before or after sunrise or sunset. This is the optimum viewing period as the sun reflects off the space station and contrasts against the darker sky.

Visible is the maximum time period the space station is visible before crossing back below the horizon.

Max Height is measured in degrees (also known as elevation). It represents the height of the space station from the horizon in the night sky. The horizon is at zero degrees, and directly overhead is ninety degrees. If you hold your fist at arm’s length and place your fist resting on the horizon, the top will be about 10 degrees.

Appears is the location in the sky where the station will be visible first. This value, like maximum height, also is measured in degrees from the horizon. The letters represent compass directions — N is north, WNW is west by northwest, and so on.

Disappears represents where in the night sky the International Space Station will leave your field of view.

Astronomical Horizon

Important: The International Space Station orbits with an inclination of 51.6 degrees. This means that, as it orbits, the farthest north and south of the Equator it will ever go is 51.6 degrees latitude. If you live north or south of 51.6 degrees, the ISS will never go directly over your head- this includes places like Alaska. Spot The Station may not properly inform you of all visible space station passes in these locations. Spot The Station’s sighting opportunities pages will give you a list of all possible space station sightings for your location.

The space station looks like an airplane or a very bright star moving across the sky, except it doesn’t have flashing lights or change direction. It will also be moving considerably faster than a typical airplane (airplanes generally fly at about 600 miles (965 km) per hour; the space station flies at 17,500 miles (28,000 km) per hour).

Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every “superstar,” every “supreme leader,” every saint and sinner in the history of our species lived there–on a mote of dust suspended in a sunbeam.
